ARTEMiS

Advanced Real-Time ElectroMagnetic Simulation

For users of the MathWorks’ Simscape Power Systems™ (formerly SimPowerSystems™) Toolbox wanting to accelerate or simulate power system models in real-time, ARTEMiS provides enhanced solvers and algorithms to ensure the reliable, accurate and fast fixed step-length computations, essential for high fidelity, high-performance real-time simulations. ARTEMiS was designed from the ground up to support real-time implementations of power systems simulations, enabling hard real-time computation speed while preserving accuracy.

Highly Accurate Solvers and Models Designed for Fixed-step Hardware-in-the-Loop Simulation

It is a fundamental constraint of real-time simulation that the model must use fixed-step integration solvers. In stiff systems like power electrical circuits, the traditional approach is to use a variable-step solver for resolving the high-frequency components in the behavior of the system. Because the time to solve at each time-step is non-deterministic, these solvers have to be replaced with fixed-step solvers, which can sometimes introduce errors into the solution.

ARTEMiS implements innovative fixed-step solvers and efficient computational techniques that improve the computational performance of Simscape Power Systems, to allow you to develop real-time simulations with your power systems models.

Because these are deterministic fixed step algorithms, you can create robust, accurate real-time simulations of your power system at significantly higher performance than with Simscape Power Systems without ARTEMiS.

A Variety of Solvers and Methods for your Specific Simulation Challenges

ARTEMiS-SSN: The State-Space-Nodal solver of ARTEMiS allows to simulate complex systems and circuits without any switch/breaker number limit in real-time

ARTEMiS-SSN also feature an industry-unique in-step parallelization feature that allow real-time simulation of coupled systems with up to 750 nodes without algorithmic delays, such as distribution grids composed of very short line sections.

Unique features like surge arrester iteration in real-time and rotating machinery that does not require any numerical snubbers

Optimized Solvers for Real-time Simulation of Power Systems and Industrial Drive Circuits

The new solvers introduced by the ARTEMiS are proven to be highly accurate and stable over much larger time steps than with the Trapezoidal fixed-time-step algorithms used by Simulink. Furthermore, ARTEMiS includes special power-circuit-specific algorithms for addressing typical problems encountered when converting your Simscape Power Systems model to real-time.

In circuits with up to 100’s of switches, the ARTEMiS-SSN solver dynamically computes the system’s equations using optimized factorization methods in real-time without spikes in computational time when switch operates, unlike regular SPS model. Similarly, strategies to avoid algebraic loops and non-deterministic iterative calculations are included. These allow fixed computation times per step and interruption-free simulation in real-time.

ARTEMiS integrates fully into the Simulink environment in the form of a Simulink blockset, and is fully compatible with Simulink Coder (formerly Real-Time Workshop) for real-time execution, or simply for accelerating the model.

ARTEMiS combined with RT-LAB, allows you to convert your Simscape Power Systems schematics into real-time simulations. This allows the distribution of a large, complex power systems model over several processors and cores in order to get the computational power required to achieve high-performance, real-time execution on the eMEGASIM real-time simulator.
